colour over tlie eyes. Anterior wings black, with 
numerous cream-coloured or fulvous stripes dividing 
the ground colour into many triangular, quadrate, 
and linear spots. The hinder wings are reddish- 
yellow, with several large angular black spots to- 
wards the posterior margin. Abdomen reddish or 
fulvous with a macular or continuous black hand 
down the centre. 
The caterpillar is brown, with several yellow 
tubercles on each segment, bearing tufts of hair : 
head and membranous legs yellow. (Plate XIX. 
fig. 4.) It feeds,” says Abbot, “ on several species 
of mimosa, commonly called the sensible briar, 
panting briar, &c., as well as on some other plants. 
It spun up June 10th, and on the 20th September 
the moth came out. In Virginia it spins in April, 
and comes forth in May. This is not a common 
kind. The caterpillar, when kept in confinement, is 
apt to die before it changes to a chrysalis.” The 
chrysalis is of a delicate lilac colour. (Plate XIX. 
fig. 5.)
